Catch locations/variants

[jaws7777]

Thought i would start a threat regarding the topic instead of derailing dr.b's thread. At the very least we could just share our thoughts on the subject. Me personally its more of a curiousity think as i find cb's attractive too.

Technically speaking it is possible for them to move around up and down the rivers. That's why it's sp. the sp. is just where its collected. So theoretically an endli could've been born in one place but is caught in another. That's why if we could get some DNA tests to clarify if there's really any big differences it would help a lot. Something else to think about is if they have food in the area why leave? If they're born in the area there's obviously favorable conditions for the parents so what's to say there's not favorable conditions for the offspring? Like I said I can't say which is true, but this is what I think.

Maybe we can all update the lap endli sticky with more info. See we dont know if the conditions where they are born could sustain adults... kind of like sharks that are born in lagoons then head out to sea when they are grown.

This is kinda where it gets complicated, as i understand it, Dabola is a town just north of faranah. Both of these areas are in Guinea. Both of these areas reach into the Niger river at different points, which is where I assume our Bichirs come from. Dabola is in the red circle up top and Faranah is the bottom cirlcle, the blue line is the Niger river.

I could be completely wrong though. This is completely based off my owns observations.

Also, wouldnt wanna derail B's thread anymore. This would be a good, separate thread though for sure.

Thats kind of how i see it too. I kind of the think the names we go by for the lap and endlis are sort of b.s ?

Not talking about sp. Dabola or any of the sp koliba, sp.kokotons to me those are less confusing

One question I have is are these being used as food? Are they being transplanted to other pets of the river for such a thing? Years of this lead to different groups? To be easily harvested. Just wondering.

Good point/question

For some reason i have a hard time beleiving an endli faranah (example) purchased today will look the se as one purchased in 6 months. Maybe im wrong though.

Dr.B very curious to see your old endli dabola and new one together

Maybe just the water/surrounding they are in and grow up in that make them have different colors.

I'm guessing the same thoughts, adding the food source.

I remember seeing a documentary a while back about the Congo river and they mentioned how many of the species of fish there were basically stuck where they were at due to the strong currents of the river and it had led to many unique fish we see today.

This kind of explains what Im talking about: http://www.livescience.com/4910-freaky-fish-congo.html
"Using the latest remote sensing technologies, and with much on-the-ground sampling and analysis, we are beginning to get a much clearer picture of just how the hydrology of the river has played a major role in isolating fish populations."

We are talking different river systems but the fact that some groups of bichir could be isolated from others for whatever reason has led to unique physical characteristics with different catch locations. Some seem subtle but others seem more prominent.

Ive never really kept endli before now and the one thing I did like after seeing the one that jaws7777 had was the elongated, flattened head that was on the Dabola Endli (Tinkisso River). While I kind of see the trait in endli in general, it just seems more pronounced in this catch location.

I guess it really does not help when suppliers to the fish trade decide to name based off the catch locations and then as time progresses they seem to get renamed. lol

Substrate plays a significant role for skin pettern we see on these bichirs. I think its kind if a defensive mechanism to be safe from predators.

This is what causes the variations in looks in simple terms, besides genetics that is. With wild animals they can change their phenotype to an extent to allow them to cope with their surrounding better and survive. Now from that I'd assume a fish overtime looking a certain way to survive, once caught and brought into a tank will always look closer to what it once did than say the same species caught from another location which needed a different phenotype.

And Dr. B explained the sp. which indicates location which would further indicate a general look that comes from that area.

I agree with what humanbean said to an extent, but the type of water also effects coloration (there's honestly a lot of variables), if you look at old threads of the "black gatf" it was thought to be another species separate from that of gatf, but Chicx later did a study/experiment with a gatf he purchased and found that in a black water setup over time it began to turn black, but these are open water swimmers for the most part so that may be a factor.
